LOCO WEED. We discovered this native SW perennial growing very high up east of the cost of the Sierra at above 6500′. Damn it gets chilly up there. Herbaceous perennial that emerges with large, bold, silver-blue leaves. Sprawling to several feet wide in a full, hot position with exceptional drainage. All summer huge white goblet like flowers unfurl from curiously colored gray buds. You can literally watch the flowers open in the evening. They glow in the moon light and emit a soft fragrance. By 2:00 the following day the flower has withered. <sad face> but more are in the wings. Begins blooming in late June and repeats to frost. Completely deciduous (gone) in winter. Good drainage in a hot position- where the soil warms early. Spectacular. Toxic- but what garden plants are not? High deer resistance. Native to the american southwest and northwest Mexico. It has become naturalized in arts of the Willamette Valley, Columbia Gorge, and Eastern Oregon. Rarely seeds itself in our climate. The seedpods that develop following the flowers are round and spiney.
